Solve for x in x plus 1 over x equals -7 over x - 12?
You have : -------------- ( x + 1 ) / ( x ) = ( -7 ) / ( x - 12 ) Multiply both sides by ( x ) ( x - 12 ) and get : ( x + 1 ) ( x - 12 ) = ( -7 ) ( x ) x^2 - 12x + x - 12 = -7x x^2 - 4x - 12 = 0 Factor the above : ( x - 6 ) ( x + 2 ) = 0 There are two roots : x = 6 <------------------ x = -2 <---------------

Which of the following is a solution of 12x - 7 > 6?
12x - 7 > 6 This is an Inequality, In simplistic form treat the inequality as an 'equals'. Hence 12x - 7 > 6 Add '7' to both sides 12x > 13 Divide both sides by '12' x > 13/12 ( = 1 1/12) Verification. When x = 1 12(1) - 7 = 12 - 7 = 5 , Which is NOT greater than '6' When x - 2 12(2) - 7 = 24 - 7 = 17 ( which is greater than '6' So any number greater than (>) '1 1/12 ' will satisfy the inequality .
